Summary & Overview
CPT 0713T: Atherosclerotic Plaque Stability Assessment from Noncoronary CTA
CPT code 0713T covers a specialist’s review and written interpretation of software-processed noncoronary CTA data to assess atherosclerotic plaque stability. This imaging interpretation and advanced post-processing report is clinically significant because it provides actionable information about plaque characteristics that can influence risk stratification and management planning for cardiovascular disease at a national level. The code reflects growing use of advanced imaging analytics and vendor or platform-derived outputs integrated into clinical reads.
Key payers addressed in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for the service, typical sites of care, and which payers commonly encounter coverage questions for such advanced CTA interpretation services. The report summarizes benchmark considerations, discusses payer coverage patterns and policy themes where available, and highlights billing and documentation elements relevant to payers and providers. Where payer-specific policy details are not available in the input, the publication notes that Data not available in the input. The content is intended for national audiences interested in imaging reimbursement, health plan policy, and clinical integration of advanced CTA post-processing into cardiovascular care pathways.
Billing Code Overview
CPT code 0713T describes a professional interpretation and report in which a provider reviews software-processed noncoronary computed tomography angiography (CTA) data to assess atherosclerotic plaque stability. The service focuses on analyzing imaging-derived plaque characteristics and producing an interpretive clinical report.
-
Service type: Diagnostic imaging interpretation and advanced image post-processing
-
Typical site of service: Outpatient imaging centers or hospital radiology departments where noncoronary CTA studies are acquired and post-processed

Clinical & Coding Specifications
Clinical Context
A typical patient is a 65-year-old individual with known peripheral arterial disease or carotid atherosclerosis referred for noncoronary computed tomography angiography (CTA) to evaluate plaque characteristics after prior abnormal duplex ultrasound or symptomatic transient ischemic attack. The imaging center acquires high-resolution noncoronary CTA images (for example carotid or peripheral arterial segments). Specialized software performs plaque analysis to quantify features such as calcification, lipid-rich necrotic core, fibrous cap thickness, and positive remodeling. The interpreting provider (typically a vascular medicine specialist, neuroradiologist, or cardiovascular imaging radiologist) reviews the software-processed data, integrates clinical history and image quality, and generates a formal report assessing atherosclerotic plaque stability and vulnerability. Results inform risk stratification and multidisciplinary decision-making for medical therapy optimization, surveillance interval planning, or referral for endovascular or surgical intervention. Typical site of service is an outpatient radiology/imaging center or hospital outpatient department. Service type: diagnostic imaging interpretation with software-assisted quantitative plaque assessment documented in the medical record.
